EcoFlow DELTA Pro 3 vs Segway Cube 1000
Side-by-side on the specs that decide it — surge, capacity, runtime and price.
Both models' specs verified against manufacturer listings · Last updated
The short answer
Segway Cube 1000 costs $2900 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro 3 holds 300% more energy (4096Wh vs 1024Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro 3 has 3600W more surge headroom (8000W vs 4400W) — that decides whether a fridge, pump or AC compressor will actually start.
- Segway Cube 1000 is 84.6 lb lighter (28.4 lb vs 113 lb).
- EcoFlow DELTA Pro 3 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
EcoFlow DELTA Pro 3
The most complete large unit here. 4096Wh, 4000W, 8000W surge and 2600W of solar — it does everything the F3800 does with less weight.
Best for: Whole-home backup buyers who want maximum solar recharge speed.
Where it falls short:
- $3,699 is a serious investment
- Overkill unless you're backing up a whole home
Segway Cube 1000
Segway's stackable home unit brings a strong 2,200W output at 1kWh and a modular design, though the cube form factor is bulkier than flat rivals.
Best for: Buyers who want a stackable, expandable home system starting at 1kWh.
Where it falls short:
- Bulky cube shape
- 3-year warranty
